The following minimal code
disp('there is a db point set at this line')
displays the following :
Sending pmode lab2client to the MATLAB client for asynchronous evaluation. "
with this error message coming next :
Undefined function or variable 'MPI_PROF_VECTOR'.
Any clue ?

I suspect the debug breakpoint is interfering with the data transfer from the spmd block back to the client.
I suppose the only workaround is: don't put a breakpoint there!
Starting in R2020a, you can invoke mpiprofile directly from the client, so you can do this instead:
% do stuff
I believe this approach should not be affected by the presence of breakpoints.
